We report on the travelling-wave parametric generation which employs a
temperature-tuned LBO crystal pumped by a approximate to 1 ps dye-las
er source. Pulses of good spatial quality, tunable from 0.8 to 2 mu m,
are obtained with pump pulses of a few microjoules. Temporally struct
ured pump pulses allow for the lower thresholds and the shorter time d
urations.
